CAN-END-MARKING ATTACHMENT FOR SEAMIN G MACHINES OR THE LIK.-

Application filed September T 0 all whom it may concern: 1

Be it known that I, PETER Know, a citizen of the United States ofAmerica, residing in the borough of Brooklyn, county of Kings, city andState of New. York, have N invented certain new and useful Improvementsin Can-End-Marking Attachments for seaming Machines or the like, ofwhich the following is a specification. This invention relates toimprovements in can end marking attachments for seaming machines or thelike, and aims to provide improvements therein. The invention pro videsa simple and compact mechanism adaptable as an attachment to-the can endfeeding mechanism .of seaming machines or the like, and isespeciallyintended as an attachment forthe can end feeding mechanism ofthe. Wilson & Sumner seamlng machine 1 described in Patents No.1,203,295, dated October 31,1916, and No; 1,250,406, dated December 18,1917. The present attachment may be incorporated in this machine with-'out involving anychangein the design or construction thereof, exceptthe substitution of the bracket for supporting the can end feedingmechanism by another bracket provided with bearings for the shafts ofthe marking attachment. to

trated in the accompanying drawings.

Referring to said drawings, Figurel is a top plan view of the receivingend of a Wilson & Sumner seaming 35 machine, showing the can end feedingmechanism together with the marking at tachment forming the'subject-matterof the present improvement;

Fig. 2 is a cross-section on the line 2--2,

4.0 Fig. 1;

Fig. 3 is a Fig. 2;

Figs. 4 and 5 are detail views of the marking means.

Referring to said drawings, numeral 10 sectional view on the line 33,

designates the marking attachment. as a whole, which is convenientlymounted on the same bracket 11 which serves to support the can endmagazine 13, from the bottom of which magazine can ends are separatedone at a time by suitable means, as a knife 15. Means for separating thecan ends from the bottom of the stack in the magazine may be of anysuitable construction, being An embodiment'of the invention is illusprab y c ns ucted. subs an ia a cor-dance with the mechanism shown inVilson 8: Summer Patent No. 1,203,295. From the bottom of the magazinethe separated can ends fall into or upon a feed-way 20, the can endsbeing supported at one side in a groove 22 in a semi-circular notch 23in a revolving disk or turret 25, and at the other side in an edgegroove-27 in a strip 28 concentric with the axis of the shaft 30 onwhich said disk 25 turns.

Numeral designates a station where the cans and can ends are joined,that is, the can ends are placed upon the open ends of the can bodies.The mechanism at station 35 may be of any suitable type, beingpreferably substantially the same as that shown in Wilson & SumnerPatent No. 1,203,295.

The marking attachment 10 is located intermediate the can end magazineand the joining station 35, and the joining station 35 and the can endmagazine are preferably separated a distance of not more than threenotches of said turret 25.

The marking attachment consists of two rotary parts 40, 41, turning onaxes at right angles to one another. One of these rotary parts, hereshown as the part 40, is in the 7 parallel and immediately adjacent tothe plane of the feed-way 20. This rotary disk turns immediately underthe can ends as they are fed past the same in the feed-way, and turns inthe space between the can end and the can body. traveling beneath thesame, and with" it toward the joining station 35. a

The other rotary part 41 is also preferably in the form of a diskturning on a horizontal shaft 45. The shaft 45 fits in horizontalbearings 47 in the bracket 11, and the vertical shaft fits in verticalbearings 49 also formed upon said bracket.

The shaft 45 extends across the feed-way 20, and is preferably gearedtothe shaft 43 by means of bevel gears50, 51, so that the shaft 45 servesto turnthe shaft 43. The shaft 45 is preferably driven from the shaft 30of the turret 25, as by means of bevel gears 53, 54. The ratio -oftheigears' 53, 54 is such in relation to the radius of the disk 40, thatthe peripheral speed of the disk 40 corresponds to the peripheral speedof the turret 25 that is, of, the can ends carried a eng by sai turret,and the pe phe l Cir speed of the disks 10 and ll is preferably thesame.

The bracket 11 is provided with a slot or opening 57 therein, whichpermits the disk 41 to project through the bracket and to make contactwith the upper side of a can end fed along beneath the same in thefeedway 20.

The rotary disk 40 is provided with a marking die 60 upon its upperface, as shown in Figs. 4 and 5, and the rotary disk il is provided witha corresponding or matching marking die 61 projecting from itsperiphery, as indicated in Fig. 4:.

The disks 40 and 41 are close enough together to just permit of thethickness of the metal forming the can end to pass between the markingdies 60, 61, as shown in Fig. 4-.

The disks carrying the marking dies are so timed as to come togetherjust as acan end passes between the disks. Consequently, as the can endpasses between the marking dies, it will be marked or indented by thedies.

The marking dies are preferably readily removable to permit of thesubstitution of differently marked dies from time to time, during thetime that the machine is being used. Conveniently, the marking dies fitin corresponding slots 63, 64, in the disks 10, 41, being held thereinby screws 66 or the like.

To prevent uneven or unequal movement of the two disks A0, 41, due toback-lash or looseness in the gears 50, 51, a brake 70 is convenientlyprovided to act upon the shaft 43, so that said shaft is turned againsta constant resistance. The teeth of the gears are thereby held steadilyand constantly in contact, and consequently, when the dies 60, 61 areonce set so as to match, they will continue to match as they cometogether during subsequent rotations of said disks.

Modification of the structure specifically illustrated and described maybe made without departing from. the idea of invention.

What is claimed is:

1. A marking attachment for can end feeding mechanism, comprising afeed-way for individual can ends, and a pair of rotary parts turning onaxes at right angles to one another, having matching marking diesthereon, one of said rotary parts being a disk turning in a planeparallel to and immediately adjacent the plane in which said can endstravel in said feed-way, said can ends being adapted to pass betweensaid rotary parts and the marking dies thereon.

2.
